Navigating real estate investment in New York City requires a deep understanding of local tax law. City-specific regulations present challenges that often surface only after transactions are underway. For both investors and practitioners, mastering the city’s unique tax structure is now a prerequisite for closing deals without costly surprises.

Jarrett Kalish, founder of Kalish Law LLC, draws on experience from the New York City Department of Finance, Ernst & Young, Baker McKenzie, and service as the city’s administrative law judge for tax matters. This background gives him a comprehensive view of both enforcement and advisory perspectives in New York’s taxation of the real estate industry.

Kalish came to real estate tax as a law student through the American Bar Association’s “Tax Law Challenge,” where he encountered a problem set focused on Section 1031 exchanges and other tax issues related to investing and managing real estate. “My interest has always been tax law, not real estate specifically, but there’s so much overlap between tax law and real estate, particularly inside New York City,” he says.

Plan Early, Save More

Transferring real estate should be thought of in the same manner as transferring a business and the tax planning should be handled similarly. Kalish stresses the importance of proactive tax diligence at the earliest stages of a transaction.

“If you’re on the buy side, it is wise to perform tax diligence before committing to a deal structure,” Kalish says. This means assessing the property, as well as any holding and operational companies, for hidden tax liabilities and understanding how the acquisition fits into the investor’s broader structure. Buyers must also plan for eventual exits, as early decisions often determine the tax consequences when properties are transferred or inherited.

Sellers should proceed in a similar manner. Kalish advises that sellers should conduct thorough self-assessments before listing a property. “You want to be doing diligence on your property, holding, and operational companies, because you don’t want to hear about potential exposures for the first time when the buyer finds them,” he says. Identifying and addressing issues early allows sellers to develop strategies to preserve deal value and avoid last-minute disruptions.

New York City’s Distinct Tax Rules

New York City’s tax regime is distinct from other U.S. markets. Several city-level taxes directly affect the real estate industry. Aside from the real property transfer tax (RPTT), the City also imposes the unincorporated business tax (UBT) and a commercial rent tax (CRT).

The UBT stands out for its application to many LLCs and partnerships in the real estate industry. At the same time, there is an exclusion for certain entities that hold, lease, or manage real property. Qualification for the exclusion needs to be approached carefully, as those that do not qualify face substantial tax liabilities. “It’s an entity-level tax on LLCs and partnerships that’s unusual,” Kalish notes.

The commercial rent tax adds another layer. In New York City, tenants pay a tax on the rent itself — a requirement rarely seen elsewhere. “The tenant pays a tax on the rent,” Kalish says, highlighting how this increases occupancy costs and alters lease negotiations.

Another notable feature is the city’s treatment of transfers of economic interests. Many transfers of LLC interests trigger the real property transfer tax, even when the underlying property does not change hands directly. In some jurisdictions, such transactions would not trigger a tax event. Kalish explains, “Transfers of LLC interests can be taxable under the real property transfer tax, even if the property itself isn’t what was transferred.” Investors must therefore consider tax implications in deals that would be non-taxable elsewhere.

Enforcement, Audits, and Disputes

After years of backlog and underfunding, New York City is investing in more efficient processing of complex tax cases. Recent policy changes have increased the resources devoted to tax enforcement and dispute resolution.

“The city is starting to invest in those resources, which means complex fact patterns that were getting deprioritized are now being reprioritized,” Kalish says. This shift is expected to bring faster resolutions but also signals a likely rise in audits.

The Tax Appeals Tribunal serves as the city’s main venue for tax disputes. Most cases settle before a full hearing, but the tribunal process requires both sides to weigh their positions carefully. “The tribunal provides an opportunity to show the full case to a judge, while the city has to more seriously consider its risks of litigation,” Kalish says. The involvement of different legal teams at the tribunal stage often leads to settlements, as fresh perspectives can break impasses.

Legal Uncertainty for Investors

Legal developments continue to create uncertainty for investors and their advisors. Kalish points to Matter of Forest Hills, a case he decided as an administrative law judge, which addressed whether the city could collapse multi-step real estate transactions into a single taxable event.

In that case, each transaction step was non-taxable on its own. The city argued for treating the steps as a single transaction to impose tax. The appellate process affirmed the city’s approach, establishing precedent that gives tax authorities broader leeway to collapse complex deals. The ruling, however, left gray areas for practitioners structuring similar transactions. “We have tremendous uncertainty on how that law should be applied,” Kalish says. Advisors must navigate a landscape with few clear boundaries.

Risk Tools: Insurance and Financing

The tools available to manage real estate tax risk are evolving. Tax insurance is increasingly common, offering coverage for identified tax exposures in a transaction. This allows buyers and sellers to proceed with deals that unresolved tax questions might otherwise derail.

“Tax insurance provides coverage against identified potential liability and can be used in the M&A context to get the purchaser comfortable about what they’re buying,” Kalish explains. While most commonly used in mergers and acquisitions, and with respect to renewable energy tax credit transactions, the product is also utilized with respect to operational planning and refund claims, reflecting its growing appeal among sophisticated investors.

Tax insurance is an available tool for those in the New York City real estate industry who seek certainty regarding treatment under the UBT, CRT, or RPTT.

Expect More Audit Activity

The current political climate in New York City points to more aggressive tax enforcement. Mayor Zohran Mamdani has prioritized creative ways to boost tax revenue, while Governor Kathy Hochul’s reluctance to raise taxes adds further tension to policy decisions.

For real estate investors, this means a higher likelihood of audits, especially for transactions involving LLCs and complex entity structures. “I could see the real estate industry being an outsized target of audit enforcement,” Kalish warns. “There’s a lot of low-hanging fruit by looking through LLCs and checking on real estate transfers and UBT filings.”

Adoption of artificial intelligence is expected to accelerate this trend. Kalish predicts AI will allow tax authorities to review historical transactions more efficiently, raising audit risk on past deals.

How Technology Shapes Practice

Kalish, like many specialized attorneys, is using technology to increase efficiency while recognizing its limits. AI now assists with routine tasks and first-draft research but is not yet capable of handling complex tax analysis.

“AI can handle mundane items and get routine work done faster,” he says. “The tax research databases all have AI functions that can help get a first draft of analysis together, but it’s not at a place yet that helps the core of my practice.”

This balanced approach is becoming standard among legal professionals who weigh efficiency gains against the need for expert judgment.

Conclusion: Integrate Tax Strategy Early

For real estate investors in New York City, the message is clear: tax planning must be an integral part of deal strategy from the outset. The city’s unique tax environment, combined with increased enforcement and shifting legal precedents, presents both risks and opportunities. Investors who engage specialized advisors early, conduct rigorous tax diligence, and consider new risk management tools will be better positioned to navigate this landscape and complete transactions. As enforcement resources grow and technology advances, the need for a proactive tax strategy in New York real estate has never been greater.
